What is the percent increase formula?

Percent Increase = ((New Value − Original Value) / Original Value) × 100. A positive result means an increase; a negative result means a decrease.

How do I calculate a percentage increase?

Subtract the original value from the new value, divide by the original value, then multiply by 100. Example: from 80 to 100 → (100−80)/80 × 100 = 25%.

What is the difference between percent increase and percent change?

Percent increase specifically measures growth (positive change), while percent change can be positive or negative. The formula is the same; a negative result indicates a decrease.

Q: Can I calculate a percentage decrease with this calculator?

Yes. If your new value is lower than the original, the result will be a negative percentage, indicating a percent decrease.

Percent Increase Formula

The percent increase formula calculates how much a value has grown, expressed as a percentage of the original value.

Percent Increase Formula

Percent Increase = ( (New − Original) ÷ |Original| ) × 100

How to calculate percent increase — 3 steps:

Subtract the original value from the new value to find the change.

Divide that change by the original value (use its absolute value).

Multiply the result by 100 to express it as a percentage.

Example: A salary rises from $50,000 to $60,000.
Change = $60,000 − $50,000 = $10,000
Divide: $10,000 ÷ $50,000 = 0.2
Multiply: 0.2 × 100 = 20% increase

Frequently Asked Questions

The formula is: Percent Increase = ((New Value − Original Value) / Original Value) × 100. A positive result means the value increased; a negative result means it decreased (a percent decrease).

Three steps: (1) Subtract the original value from the new value. (2) Divide by the original value. (3) Multiply by 100. Example: from 80 to 100 → (100 − 80) / 80 × 100 = 25%.

The math is the same. "Percent increase" specifically implies growth (a positive change), while "percent change" is a neutral term that covers both increases (positive) and decreases (negative). If the result is negative, it's a percent decrease.

Yes. If the new value is lower than the original, the result will be a negative percentage. For example, from 200 to 150: (150 − 200) / 200 × 100 = −25% (a 25% decrease).

Percent increase from zero is mathematically undefined (division by zero). You cannot express growth from zero as a percentage — the calculator will warn you in this case.

A 20% increase on 50 gives you 60. Calculation: 50 + (50 × 20/100) = 50 + 10 = 60. Use Mode 2 ("Apply % to a Value") on this calculator to solve this directly.

A 10% increase on 100 gives you 110. Calculation: 100 + (100 × 10/100) = 100 + 10 = 110.

Enter your current salary as the Original Value and your new salary as the New Value. The calculator will show you the exact percentage raise. For example, $40,000 rising to $44,000 is a 10% salary increase.
